Machining a Stuart 10V Steam Engine. Harold Hall

Workshop Projects

Having noticed a viewer had arrived at my web site by searching for “Stuart 10V”,
I went to the Google page to see where I was in the ranking. Whilst there, I visited
a metalworking forum that was listed and found the subject being raised was making
a Stuart 10V in a workshop having just a lathe.

The brief articles that had appeared in the Model Engineer at that time to illustrate
machining processes, using some parts from a Stuart engine, were though using both
a lathe and a milling machine. This being the catalyst for the comment on the forum,
a comment that a number of others agreed with. The train of thought was that an article
for the lathe only workshop would be a good idea and if produced should be at a level
to suit the novice metalworker.

Having around 15 years previously made a 10V using just a Hobbymat MD65 lathe and
a small drilling machine I suggested to the editor that I could possibly satisfy
the forum members wishes, and no doubt others, by producing a series to cover the
subject in that way. It was agreed that I do this and that it should have sufficient
detail for those with limited workshop experience, I expect though that the more
experienced will find some of the processes different to those that they would use
and therefore these pages are worth studying for them also.

Lathe with milling machine

Whilst these pages are based on a machine shop without a milling machine very much
of what is suggested is also applicable even if a milling machine is available.

I consider that the viewer having a milling machine will have little problem with
transferring a small number of the operations from the lathe to the milling machine.
Even with that done much of what is suggested for the part if machined on the lathe
will still be applicable on the milling machine. The workshop owner having a milling
machine should not therefore assume that this is not for him, or her.

Lathe without milling machine.

Photograph 1 shows both engines that I made using the method, with the 10V shown
individually in Photograph 2 and the 10H Photograph 3. The initial pages are though
based on the 10V but then concludes by showing how to machine the few components
that are different in the case of the 10H. Stuart have kept the part names and numbers
the same for the two engines so those I use will be applicable to both.

If you are experienced in the use of the lathe then you can bypass these early pages
and go straight to “Construction Commences”, page 4, where the photographs start.

Others may also like to do that and then come back to the earlier pages later.
